1. An imaging flow cytometer for passing a sheath blow having a sheath liquid around a sample flow containing particles to be detected, irradiating a sample fine flow with light, and detecting light signals from the particles, comprising:

  • an irradiation light source for illuminating particles in the sample fine flow,imaging means for imaging particles by receiving particle light images in a sample flow region of the sheath flow, andan image processor for processing the images taken by said imaging means, wherein;

    said imaging means is of the split scanning type capable of repetitively scanning a band-shaped scanning region of an imaging area limited to a certain range of the imaging area within one field period, andsaid sample flow region is defined within the band-shaped scanning region of the imaging area.
